runtime build stuck when DOTNET_CLI_USE_MSBUILD_SERVER is set to 1

[smasher164]

Issue Description

On the latest (as of dotnet/runtime@41ae1ae) commit of the runtime, the build gets stuck indefinitely. I tried building five times, pulling in latest changes, and clearing all artifacts. The build displays and gets stuck at Microsoft.NETCore.App.Runtime -> which is in the packing stage. It went up to one hour for one of the executions, before I killed it.

Steps to Reproduce

0. Ensure that DOTNET_CLI_USE_MSBUILD_SERVER is set to 1.
1. .\build.cmd -allconfigurations

Unable to attach binlog when building with -bl since the build was cancelled early.

Expected Behavior

Build is successful.

Actual Behavior

Build is stuck on Microsoft.NETCore.App.Runtime ->.

Analysis

Steps taken to debug:

1. Attached a debugger to the host process, which seemed to just be stuck in System.Threading code.
2. Process tree just shows a bunch of MSBuild.dll invocations:
   
3. Using procexp, I couldn't pinpoint a handle that referenced Microsoft.NETCore.Runtime.
4. @hoyosjs suggested rebuilding with DOTNET_CLI_USE_MSBUILD_SERVER set to 0, and the build was successful.

Perhaps there's some deadlock in the msbuild server?

I tried it with dotnet SDK 7.0.101 and it worked on my computer. Tooked ~ 2hours though for clean build and 10 minutes for rerun.
@smasher164 Was it clean build? Any other hints on repro steps? Can you still repro it? Was this repro consistent?

Closing because I can no longer repro this. Thank you!
